- The ovulation rate and the number of ova shed (mean ± SEMs) and weight of the left or right ovary of intact rats, or rats subject to left (L-laparatomy) or right (R-laparotomy) laparotomy, and those subject to left (L-ULO) or right (R-ULO) ULO were measured at the predicted estrus day
-
a
p < 0.01 vs. respective laparotomy group (Fisher’s exact probability test)
-
b
p < 0.01 vs. respective intact group (Kruskall Wallis test, followed Dunn test)
-
c
p < 0.01 vs. respective laparotomy group (Kruskall Wallis test, followed Dunn test)
- ***data statistically analyzed by ANOVA followed by Tukey test
- **represents the number of ova shed by the ovulating rat
- *Number of ovulating animals/number of treated animals
